Are you driving your truck now or is it close to running with the 216 or are you in the middle of restoring it?
Stock brakes are fine for a stock 216 but not sufficient for higher powered engines..
If you're currently driving it redoing the stock brakes is fine.
If you're restoring it and have designs on repowering it, now would be the good time to upgrade the brakes to a dual master cylinder and disc's up front. Adding a power booster will make it stop like a modern vehicle.
Good luck
